> startFileInternal() increments genStamp and passes it to FSDirectory.addFile() as a parameter,
while the addFile() simply ignores the generationStamp parameter.
> We should remove the call of nextGenerationStamp() in startFileInternal() and eliminate
the redundant parameter in FSDirectory.addFile().
